Re: GRE Physics Practice

As you have asked about the Graduate Record Examination (GRE) physics practice questions, I am givng you some information about it
The figure above shows two objects with masses and velocities as indicated. The objects are moving on a horizontal, frictionless surface. When they collide, the objects stick together. Their speed after the collision is most nearly

(A)0.67 v0
(B)0.87 v0
(C)v0
(D)1.15 v0
(E)1.73

Ball 1 is dropped from height h and ball 2 is dropped from height h/2. Which of the following gives the ratio of the speed of ball 1 to that of ball 2 just before impact? (Assume that air resistance is negligible.)
(A) 2
(B) rt2
(C) 1
(D) 1/rt2
(E) 1/ 2

A capacitor of capacitance 125 microfarads is initially charged such that the voltage across the plates of the capacitor is found to be 100 volts. If the capacitor is then connected in series to a pure inductor of inductance 0.2 henry, what is the maximum value of the current that is observed in the inductor?

(A) 1.0 A
(B) 2.5 A
(C) 4.5 A
(D) 5.0 A
(E) 10.0
